Title: Bass reflex type speaker box
Inventor: CHUMA TAKAHIRO
IPC: H04R1/02
Filed: 1987-05-22
Abstract: PURPOSE:To cut off the infrasonic component of a filter reproduced sound in a port by a filter by providing an acoustic load, i.e., a sound absorbing material in a bass reflex port. CONSTITUTION:Into the inside of the bass reflex port 11, a spherical sound absorbing material 12 of a diameter approximately equal to that of the vault in linear state is inserted with a necessary minimum friction against the surface of the vault. Also, sound absorbing nets 13 are fitted to the top and the bottom of the port 11 in order to prevent a whisling of the air. By thus providing the movable sound absorbing material 12 as an acoustic load in the bass reflex port 11, the infrasonic component of a sound that causes the air whisling can be filtered and cut.
